Hello mark:

<< treated unfairly by my teacher, why would i want to promote more people into his family when i can go to any streetcorner storefront school in america and find a new family that would treat me appropriately?

You raise an excellent point. A martial arts school may have a certain "familial quality". With luck a certain intimacy with its members exists. How many places in life can we strick/attack someone with this intensity, this intent and still be friends afterwards?

However, I already have a daddy, a mother... I do not seek another. I contend there is a serious danger to the familial quality of a school if we are not extremely aware and careful too. From the lineage perspective its a decent parallel, but beyond that narrow context, there are very real potential risks.

Merely my opinion, I could surely be mistaken,
